Not a striker, not a second striker, not a wingback... His first year in Juve so far has been filling holes and playing where is necessary, Pirlo should soon figure out where his place is and start using him on regular basis there...
The talent and potential is huge, yes, but I get the feeling that the most difficult thing for Dejan is to figure out what his job and duties are when he steps on the pitch, they are different each and every game, it's confusing and obviously not the way to help him develop his potential...
